Storage procedure
1. Whenever possible, install the circuit
breaker operator module in its assigned
switchgear enclosure or end location for
storage.
2. When the circuit breaker operator
module needs to be placed on its pallet
for storage, be sure the unit is securely
bolted to the pallet and covered with
polyethylene film at least 10 mils thick.
Indoor storage
Whenever possible, store the circuit breaker
operator module indoors. The storage
environment must be clean, dry and free of
such items as construction dust, corrosive
atmosphere, mechanical abuse and rapid
temperature variations.
Outdoor storage
Outdoor storage is not recommended. When
no other option is available, the circuit
breaker operator module must be
completely covered and protected from rain,
snow, dirt and all other contaminants.
Space heating
Space heating must be used for both indoor
and outdoor storage to prevent
condensation and corrosion. When the
circuit breaker operator module is stored
outdoors, 250 watts per circuit breaker of
space heating is recommended. If the circuit
breaker operator module is stored inside the
switchgear enclosure, and the switchgear is
equipped with space heaters, energize the
space heaters.
